What is a GIF?

GIF iconGIF stands for Graphics Interchange Format. It is a lossless, bitmap image format which became popular on the world wide web because it supports transparency and simple animations in browsers. It can support up to 256 different colours from a 24bit range of RGB values. It uses LZW compression (which was subject to patents owned by Unisys). Issues over this in 1990s, led it to be largely replaced by the PNG format in modern usage.

The file name extension for GIF files is: .gif
